Depends on what you're interested in, really. there's /r/television, /r/movies, and /r/gaming, plus subreddits for almost every tv show, movie, and game you can think of. ELI5 is fun, but I think it's a default now. /r/ifyoulikeblank is great for music, movie, tv, game, book recommendations [for example "if I like [x], what else will i like?"] /r/cars and /r/autos, along with /r/justrolledintotheshop for lols My main recommendation is to unsubscribe from shitty subreddits like /r/adviceanimals and /r/funny because they're just a waste. You're better off adding things like /r/worldnews and /r/science where you'll learn things.
